GaP Photodiodes - UV Wavelengths

Thorlabs stocks a wide selection of discrete photodiodes and calibrated photodiodes. These include Indium Gallium Arsenide (InGaAs), Gallium Phosphide (GaP), Silicon (Si), and Germanium (Ge) photodiodes, as well as Quadrant and Dual-Band photodiodes. The FGA20 provides high responsivity from 1200-2600 nm, allowing detection of wavelengths beyond the normal 1800 nm range of typical InGaAs photodiodes. In addition, we have a large variety of sockets available for all of our photodiodes.
